So you’re taking over an old or inactive anime club, and it looks like there’s a lot of dust to wipe off.
Make sure your club is still recognized.
For schools and libraries, clubs usually have to be recognized every year, so you’ll need to redo the application process or meet with the person in charge. The good thing is, if the original advisor for your anime club hasn’t left, you don’t need to make another constitution or find another advisor (unless they say they don’t want to be the advisor again).
Community clubs don’t need official recognition.
